Also call me crazy, but I don't feel that 40lbs is really that much for a solid 8 wheel drivetrain especially with transmissions. I would much rather have the weight in the drivetrain than up high. Also we kinda pride ourselves on never getting pushed and being able to push anyone.

ask the designers of that gearbox (Travis Covington from 968, and others I forgot) and they admit that it was too extreme and they only did it as a senior project. Hobbing and cutting all the gears was too much work. They plan on using the gears from the AM 2-speed next year (which appears to be what you are using); The AM 2-speed is rather light for what the functionality it provides.
